Abstract

Un procédé de routage de données d'application basé sur une règle URSP, et un équipement utilisateur sont divulgués. Le procédé fait appel aux étapes suivantes : un UE acquérant une liste de règles de politique de sélection de route d'UE (URSP) et un indicateur de description de sélection de route (RSD) dans la liste de règles URSP ; l'UE établissant une session PDU selon l'indicateur RSD ; l'UE acquérant un paramètre TD à partir de la règle URSP, et établissant une relation de mappage entre le paramètre TD et la session PDU ; et l'UE acquérant des données d'application et des paramètres correspondants des données d'application, et déterminant un trajet de routage pour les données d'application selon les paramètres correspondants et de la relation de mappage. La solution technique divulguée dans la présente demande présente l'avantage d'apporter une bonne expérience à l'utilisateur.
